Commitments and Contingencies

Litigation: We are involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, based upon consultation with legal counsel, the ultimate disposition of these matters, taken as a whole, will not have a material adverse effect on our consolidated financial statements.

Guarantees: In connection with the sale of equipment to various financial institutions, we have entered into contractual arrangements whereby we agreed to repurchase equipment at the end of the lease term at a fixed price. Our total obligations under these fixed price arrangements were $1,285 as of April 28, 2012 and April 30, 2011. We have recognized a guarantee liability in accrued expenses for the amount of $185 in accordance with the provisions of ASC 460, Guarantees, in connection with these arrangements.

Warranties: We offer a standard parts coverage warranty for periods varying from one to five years for all of our products. We also offer additional types of warranties that include on-site labor, routine maintenance and event support. In addition, the terms of warranties on some installations can vary from one to 10 years. The specific terms and conditions of these warranties vary primarily depending on the type of the product sold. We estimate the costs that may be incurred under the warranty obligations and record a liability in the amount of such estimated costs at the time the revenue is recognized. Factors that affect our estimate of the cost of our warranty obligations include historical experience and expectations of future conditions. We periodically assess the adequacy of our recorded warranty reserves and, to the extent that we experience any changes in warranty claim activity or costs associated with servicing those claims, our warranty obligation is adjusted accordingly.

Changes in our product warranties during the years ended April 28, 2012 and April 30, 2011 consisted of the following:



	April 28, 2012			April 30, 2011
Beginning accrued warranty costs	$	22,982		$	18,866
Warranties issued during the period	8,199			10,026
Settlements made during the period	(13,531		)	(14,909		)
Changes in accrued warranty costs for preexisting warranties during the period, including expirations	4,565			8,999
Ending accrued warranty costs	$	22,215		$	22,982

Performance guarantees: We have entered into standby letter of credit agreements, bank guarantees and surety bonds with financial institutions relating to the guarantee of future performance on contracts, primarily construction type contracts. As of April 28, 2012, we had outstanding letters of credit agreements, bank guarantees and surety bonds in the amount of $2,443 and $32,399, respectively. Performance guarantees are issued to certain customers to guarantee the operation and installation of the equipment and our ability to complete a contract. These performance guarantees have various terms, which are generally less than one year.

Leases: We lease vehicles and office space for various sales and service locations throughout the world, including manufacturing space in the United States and China and various equipment. Some of these leases, including the lease for manufacturing facilities in Sioux Falls, South Dakota, include provisions for extensions or purchase. The lease for the facilities in Sioux Falls, South Dakota can be extended for an additional three years past its current term, which ends December 31, 2016, and it contains an option to purchase the property subject to the lease from January 1, 2015 to December 31, 2016 for $8,400, which approximates fair value. If the lease is extended, the purchase option increases to $8,600 for the year ending December 31, 2017 and $8,800 for the year ending December 31, 2018. Rental expense for operating leases was $3,159, $3,738 and $3,513 for the fiscal years ended April 28, 2012, April 30, 2011 and May 1, 2010, respectively.

Future minimum payments under noncancelable operating leases, excluding executory costs such as management and maintenance fees, with initial or remaining terms of one year or more consisted of the following at April 28, 2012:



Fiscal years ending	Amount
2013	$	2,997
2014	2,170
2015	1,674
2016	1,598
2017	805
Thereafter	76
	$	9,320

Purchase commitments: From time to time, we commit to purchase inventory, advertising rights, and various other products and services over periods that extend beyond a year. As of April 28, 2012, we were obligated under the following conditional and unconditional purchase commitments, which included $1,000 in conditional purchase commitments.



Fiscal years ending	Amount
2013	$	1,801
2014	1,042
2015	299
2016	200
2017	200
Thereafter	200
	$	3,742

Allowance for doubtful accounts: Subsequent to April 28, 2012, we became aware of circumstances that could cause an increase in our allowance for doubtful accounts in an amount between $0 and $2,500. These circumstances arise out of a contract in China for which payment by our customer is dependent on funding from a local government entity that is not under any legal obligation to provide.

Insurance revenues: In October 2009, our subsidiary Star Circuits, Inc., which produces circuit boards for use in our products, had a fire which damaged or destroyed its key production equipment and building mechanical and structural components. Operations were stopped in this facility until new equipment was installed and the build out was completed in another building in the fourth quarter of fiscal 2010. Our insurance coverages entitled us to receive payments for business interruption, as well as recoveries for damage to the building and equipment as a result of the fire.

During fiscal 2010, we received or settled on $3,748 of insurance proceeds related to this incident. Insurance proceeds to reimburse costs to reconstruct the facility and to replace manufacturing equipment, supplies and contents resulted in gains of $1,496 during fiscal 2010, or $0.04 per share, net of taxes. Additionally, in fiscal 2010, we recorded $988 in business interruption reimbursements for extra expenses incurred during the non-operating period in cost of goods sold. There were no outstanding insurance reimbursements as of April 28, 2012.
